IMPROVEMENT IN CRlMPl-NG-MACHINES.

Specification forming part of Letters Patcnt No. 1 78,866, dated June 20, 1876; application file October 29, 1875.

To all whom it may concern:

Be it known that I, LEWIS P. LUM, of

Newbnrg, in the county of Orange and State of New York, have invented certain Improvements in Crimping-Machines, of which the following is a specification:

To describe the improved machine I refer to the annexed drawing, making a part of this specification, in which- Figure 1 represents a front View of the crimping-machine, and Fig. 2 is a side view of the same.

A A are a pair of vertical posts, made of wood, iron, or any other suitable material, standing on base-pieces B B, and carrying top pieces N N. In these top and base pieces are cut grooves in which are sliding another pair of vertical bars, 0 (l, of equal dimensions and materials as the uprights A A, to which they are held by the bolts L L and H H. The set-screws M K, having their nuts inside the pieces 0 G, serve to set the bars A.

G apart, whilethe bolts L H keep them in their positions. In the lower part of the uprights A A are two journal-boxes, J J, for a shaft, S S, which receives rotary motion from a hand-lever put on the one endV of the shaft, when the machine is used as a handmachine, or from a pulley, U, at the other end of the shaft, if the machine is used with power. To this shaft S S are fastened two belts, P P, in the slots 3 s, or otherwise.

These belts will wind around the shaft Swhen it is in motion, and pull down the former F, to which the upper ends of the belts are fastened by hooks h h, or by other means. The former F is being guided by the space left between the vertical posts A C. There is a disengaging arrangement attached to one side of the frame, consisting of a lever, Q, connection a, and shifter r T.

When the former F is pulled down so low that it strikes the projecting edge of lever Q, this lever, by means of connection a, pulls the shifting-rod r, and the fork end T forces the pulley from the feather t on shaft S, so that the pulley U will turn loose on the shaft, and the former F will stop on its downward motion. This engaging or disengaging of the power may be ,done by a clutch-coupling on the feather being moved in or out a correoccasioned by two counter-weights, W W, which are hung up on cords r 1, which run over rollers R R, and are fastened at the ends of the former F. These weights W W are pulled up, when the former F is pulled down,

by means of belts P P, and they in turn pull up the former F as soon as the pulley U is disengaged, the weights W being heavier than the former and its attachments.

To each pair of side posts A A and G O is fastened a frame, E E, and to these the plates D D, with their faces toward each other, so that they leave room enough between for the former F to pass between. These platesD form a table at the top, of a shape to suit the shape of the former F, and the former has a shape to give the leather the right crimp.

The leather, after it is cut and prepared, is laid on the top of the plates D, and, as soon as adjusted, the machine is set in motion by meansof the hand-lever Y, which secures the pulley U to the shaft S. The former F is started to come down. It takes the leather and pulls it through between the plates D, which are grooved on their faces in suitable shape, until the whole width of the crimped leather is below the bottom of the plates D. At the bottom edge are fastened two springplates, G G, which project with their lower edge close together. As soon as the leather is below this edge the machine is stopped, the former F is pulled up by the weights W, while the edges of the plates G G strip the leather from the former F, which alone ascends between the plates D D.

The setting of the plates D to the right distance between their faces to allow the former to pass between their faces with the, leather, and to give the right tension for any thickness of leather to he crimped by being only once pulled through, is only done by means of the bolts L H and the set-screws M K, and

the frame is so constructed'as to give sufficient elasticityat the same time sufficient stiffness-to insure the crimping ofthe leather.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a leather-crimping machine, the ver- 3. The lever Q, connection u, and shiftingtical stationary posts A A, made of wood, rod 71, in combination with the former F and iron, or any other suitable material, in compulley U, all substantially and for the purbination with the adjustable posts 0 0, bolts pose described.
